great for multiple guitar changes

a strap and three sets of Grover strap locks and some spare buttons make changing guitars easy.I use at least 10 guitars in a given night, and I use one strap with my wireless attached to it and can change easily from guitar to guitar with the grovers.Basically the grovers have taken the old Schaller design and reproduced them.I do not like the new Schaller design, I like the old design better, and I have a lot of guitars and they are fitted with the grovers.It is a good option to be able to just order extra sets of strap pins so I can fit them on any guitar that I want to use, without buying full sets.

Just as good as pricier models

This pair of locks are well made and are interchangeable with others using the same form factor. They don't include felt washers and the screws are a little scrawny so you may need to use your guitar's original screws if this is not a new install. Get some felt washers if you don't want the metal touching your instrument's finish. Definintely would buy again..

Have them on every guitar I own.

Compared to some, my collection is modest. Six electrics and one accustic. I have never had one mishap with any of them due to the secure cup and center lock of these strap locks. This product does its job and never fails.
